I know that the falling sound is separate from the normal "hit1", "hit2" etc. but sometimes they don't sync up which ends up with the thud occurring before the bone crack. This hasn't happened before 1.4.4. Is this a client-sided bug because this never happens with other players in multiplayer.
Video size was too large so i'm linking a comparison I uploaded to YouTube.

The "thud" is client-sided and happens whenever you hit the ground. The damage sound occurs when the server processes the fall and gives the client the appropriate damage.
